$2{\mathrm{H}}_2\mathrm{O}⟶2{\mathrm{H}}_2+{\mathrm{O}}_2$ $36\mathrm{g}$ 2 moles of ${\mathrm{H}}_2\mathrm{O}\equiv 4$ moles of $e^{-}\mathrm{s}$ $4\mathrm{F}$ of charge is required for complete decomposition. Now, $Q=I\times t$ $\begin{array}{rl}\therefore t=\frac{Q}{I}=\frac{4\times 96500}{3}& =128666\sec \\ & =\frac{128666}{3600}=35.8\mathrm{hr}\end{array}$
